Until now we used crimping pliers from other companies' products, but we needed considerable grip strength when crimping, and hands hurt when we did a number. Since changing to Hozan's pliers this time the hands will not hurt even when crimping work continuously, so the stress of work has decreased. By the way it was possible to crimp Hozan's pliers with one hand even with the grip strength of a woman who had to be with both hands so far.
